Hi, how about a workaround? I cannot write a script at all, but from Google searches on how to do stuff I created my own workaround:
1) For working brightness buttons after startup and a startup brightness of 50 % I added the following to the file /etc/rc.local (before the exit 0): bash -c "echo 0 > /sys/class/backlight/intel_backlight/brightness" bash -c "echo 50 > /sys/class/backlight/acpi_video0/brightness" 2) For working brightness buttons after a suspend I added a file named 20_Enable_Brightness_setting_keys to the directory /etc/pm/sleep.d The file contains: case "${1}" in resume|thaw) bash -c "echo 0 > /sys/class/backlight/intel_backlight/brightness" ;; esac I guess this is crude and full of possible errors/problems, but it works for me for the time being. This way the brightness after a resume is at the level it was before standby and the brightness keys on the XPS13 work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1163720 Title: Brightness control broken on XPS13 with 3.8.0-16 and 3.8.0-22 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1163720/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
